JHipster

Question

這是我在這裏的第一篇文章。我通常會盡力自己找到所有的東西，但我覺得我已經擊中了每一堵牆。我很抱歉，如果我不夠具體，但希望有人在這裏可以幫助我。 我剛開始使用jHipster併成功生成了一個項目，並將它添加到IntelliJ IDEA（使用試用版）。不幸的是，我一直無法讓應用程序運行。我繼續收到此錯誤（必須減少以適應字符限制）：

這些只是我收到的錯誤的開始。我遵循jHipster網站上列出的所有安裝程序，包括安裝node.js，npm，bower，yo，grunt，maven，git。我正在嘗試爲此使用Java 8，但沒有看到問題是什麼，我無法運行沒有錯誤的未修改生成的項目。我遵循指示將Spring添加到模塊項目結構中，但無濟於事。該項目將進行編譯但不會運行。運行「grunt serve」會啓動一個空的服務器並使用mvn spring-boot：運行會關閉上面列出的錯誤，這與僅嘗試運行Java應用程序相同。只是要注意我也嘗試使用Eclipse的相同錯誤。如果有人需要更多的信息來幫助我解決這個錯誤，我會非常樂意提供任何必要的細節。我可以弄清楚在獲取應用程序運行後應該做什麼，但是無法達到這一點。如果任何人都可以得到任何幫助，我將不勝感激。感謝大家！

它看起來像錯誤是連接到您的postgres服務器。確保你有一個數據庫名稱爲application.yml中定義的postgres。如果你不想使用postgres，你可以配置jHipster使用嵌入的H2數據庫。

這是錯誤跟蹤是相關的部分：池初始化期間異常：

com.zaxxer.hikari.pool.PoolInitializationException: Exception during 
pool initialization: Connection to localhost:5432 refused. Check that 
the hostname and port are correct and that the postmaster is accepting 
TCP/IP connections.
